{Jriginal application'fi'led December 6, 1913, Serial No. 805,068;Divided and this application filed December 21, 181%. Serial No.828,396. i

To all whom tit may 00720671111.

Be it known that 1, JOHN S. BERRY, a citizen of the United States,residing at Plainiield, in the county of Union and State of New Jersey,have invented new and useful Improvements in Windows, of which thefollowing is a specification.

My invention relates to window frames and sash construction"where thesashes are intended to be tilted inward in order toconveniently reachboth sides of the same for cleansing and repairs. To attain thisend, itis necessary to remove the parting strip or guide between the sashes outof the way of the lower sash, as well as to provide means for thepivotai action of both sashes. lhe latter is provided for in anyapplication, :Serial No. 805066, while the former is covered by thepresent application, as a division of said application, and consists ina collapsible parting strip and means for collapsing the saneautomatically by the sash in its downward movement; and to provide acombined mechanism for .accompiishing the collapsing of the partingstrip and the pivoting and locking of thesash by the movement of thesash itself. 1

To these ends, my invention consists in the mechanism hereinafterdescribed.

My invention is illustrated in the accompanying drawings, in which-Figure 1 is a perspective elevation of part of a side wall of :1V windowcasing, showing a collapsible parting strip in normal position for usewith the operating plate adjacent thereto in the sash guideway; Fig. 2,a perspective elevation of a portion of a window sash showing the"corner socket'for engaging the operating plate; rig. 3', a sideelevation of the operating plate, its supporting bracket andspring,shown in operat ng relation with the parts of the collapsible partingstrip; Fig. 4, a corresponding side elevation in section of anotherportion of the parting strip showing one of the links in pivotalconnection with the parts; Fig. 5, a cross section of the parting stripwith one of the sets of connecting links; and Fig. 6, a detailperspective view showing the construction of the movable plate and itsholding bracket-the parts being shown detached.

Referring now to the drawings-The inner strip or first beading of windowconstruction is conveniently moved out of the way by hinges; but withthe central guide or parting strip, the conditions are differentbecausethis should remain in place until the inner (lower) sash is tiltedinward, to guide the outer (upper) sash in its initial downwardmovement. The removal of the central parting strip out of the way at theproper time by the descending action of the upper sash itself, as anautomatic function, is the object of the construction shown in thedrawings to which reference is made by way of clearer definition.

C designates the side wall of the windowcasing against, and between twoof which, at opposite sides, the windows move vertically. In the face ofthe casing a longitudinal roove is sunk to receive the parting stripwhich in this instance is the coliapsible parting strip E.

The collapsible parting strip E consists of three elements, namely, (1)a trough shaped strip 6 seated fixedly in the groove provided in theside wall of the windowcasing for the parting strip; (2) within, and insliding contact outwardly with v the trough-strip 6 two side strips 6c3; and above and between the latter, in sliding contact therewith, atrough-shaped strip 6 in inverse relation to the trough-shaped strip 6Each of these elements is provided with a fixed cross pivot, 79 72 prespectively, insuch relation as to be engaged by the same link y whichlatter is preferably duplicated so as to engage in each case within andnear the outer wall of each element.

The link is bent to a slight angle in its length, as shown in Fig. l, inorder to ac commodat e the desired relative motion of the parts in theirtelescopic collapsing movement one within the other. To the same end,suitable depressions or recesses as shown in Figs. 3 and 4, are formedin the edges of the sidewalls of the collapsing elements to accommodatethe cross pivots of each in relation to the other as indicated by arrowsin Fig. 3.

Duplicates of the link-and-pivot connections are provided at givenintervals in the length of the parting strip whereby the relativeopening and closing movements'are rendered uniform throughout. Thecollapsing action of the parting strip is rendered automatic by thedescending movement of the upper, sash. To this end, a device consistinprimarily of a plate, 35, pivotally connected of the guideway of theupper sash, is promounted by an arm or arms A coiled.v spring 8, carriedupon the pivot 7 seats with .vided.

.The plate F is pivotally mounted upon a bracket consisting of a plate Fsecured to and flush with the surface, in the guideway wall ofthe windowcasing, and havingtwo inwardly projecting side arms 7, fhat and betweenthe extremities of which is affixed a cross pivot '7, upon which theplate F is one projecting arm upon the underside of the fixed plate F,and at the other upon the one of-the arms 7' of the pivotally movableplate F,-so as to hold the plate-F normally outward in the'path of theupper sashiasan outwardly inclined extension of the plate F A small sideflap 7 furnishes the means of engaging the pivot 12 before men tioned..7 I

The pivot-engagingarms f are radially proportionedto the links y, sothat the rela tive movement of the plate F coincides with that of saidlink. As the sashdescends and rides upon the inclined plate F, the plateis pressed-back to avertical position against the force of the spring;-Vand by. the said movement, the parting strip E is collapsed flushwith'the surface of the casing wall.

In order to furnish a pivot to the sashfor its tilting action, I provideupon the face of the plate F, a stud f and place upon'the outer edgeofthe sash a corresponding socket v plate g, as shown in Figs. 5 and 6 Asthe sashjdescends, the stud f enters the narrowguideopening of the plateinto the socket whichis circular. The stud 7 being longer than wide, andthe guide opening being only wideenough to admit the stud whenpresenting itself lengthwise, the stud becomes 'a lock for the sash inall except vertical move ments.

It will be seen that in the use of my invention, and withasuitablepivot' for the frontsash, the attendant has only to loosen thefront beading, tilt the lower sash inward, draw down-the upper sash andtilt Copies of this patent may be obtained for it inward also, theparting strip being autain by Letters Patent of the United States: i l.A collapsible parting strip adapted to seat and be compressed in thenormal groove therefor inthe window-casing, and adapted to be engagedand compressed by the down,

4. An actuating device for ahcollap'sible 1 parting strip consisting ofa holding plate adapted to be secured tofthe guideway in the path ofthesash, and a movable platepiv' otally secured thereto and to .thepartingstrip and normally projected outward into the path of the sash andadapted to actuate and collapse the parting strip.
